On my 13" M1 MBP I have tried every possible option to get Desktop Video to recognize my UltraStudio TB2 Mini Monitor device except the DFU mode - and that's only because I do not have another Mac with USB-C on it. Yeah, thought this terminal commands route was a long shot given how he was coming from a previous non-M1 Mac and Catalina. I am glad to be back up and running with my 3G under Big Sur! It worked for me, which made me think the leftover kernal extensions were the problem going from Catalina to Big Sur. If Desktop Video then says "No Desktop Device Detected" you have to go to System Preferences>Security & Privacy>General and the select "App Store and identified developers” and then “Allow” Blackmagic Design in the pop-up window. Open Terminal to enable SIP: At the prompt enter this command: csrutil enableĩ. After deleting the extensions, I rebooted in Recovery Mode (command-r)Ĩ. Sudo rm -rf /Library/StagedExtensions/Library/Extensions/BlackmagicUsbIO.kextħ. Sudo rm -rf /Library/StagedExtensions/Library/Extensions/BlackmagicIO.kext Sudo rm -rf /Library/StagedExtensions/Library/Extensions/Blackmagic_Multibridge_Driver.kext In my case, the commands looked like this for the three extensions: Once you reboot, open Terminal and force delete the kernal extensions.
You will get a message that SIP has been disabled.Ħ. Open Terminal to disable SIP: At the prompt enter this command: csrutil disableĤ. Uninstall Video Desktop using the uninstall program.ģ. Once I did all of this and then installed 12.0b1, it WORKED! Desktop Video recognizes the recorder and the picture displays correctly in OBS, using either SDI of HDMI.ġ. To do that, you have to boot into recovery mode, disable SIP, force delete the kernal extensions, then reenable SIP. So, I thought about getting rid of those. Then I noticed that the uninstall left 3 kernal extensions on my system: I completely uninstalled several times and reinstalled, but it was still the same. I tried installing 12.0b1 and got the same thing. The recorder was recognized, but all I saw was a black screen in OBS. I experienced the same issue as everyone else. I had Desktop Video 11.7 installed on Catalina and then upgraded to Big Sur. Thank each of you for posting your experience here.MY SOLUTION - UltraStudio Recorder 3G and Big Sur I wish BM engineering would take a real look at this with so many customers apparently having this issue. Perhaps the BM hardware received an initial firmware update with a possible bug, and that's why it worked initially but then eventually stopped working. One by one, each became defined properly in Device Mgr, started working and all became visible to Desktop Video Setup. And I tried downgrading the BM Desktop Video back to 11.7, 11.6 and several others previous levels, all without any success.Īnd then after reading this post and another BM forum posting, I merely just selected each of the 3 non-working HDMIs found in Device Mgr under "Other devices" and chose the "Update driver" option (I myself did not do any uninstallating). The rest, the 2nd, 3rd and 4th HDMIs were all listed under "Other devices" with a (?) question mark on each of them. And as others mentioned, I could see the proper setup in Device Mgr of HDMI-1. Still, I surprisingly could at least get OBS to recognize an input to HDMI-1. Upon doing some BM Desktop Video updates, going from 11.6 (maybe it was 11.7) to 12.0, the Desktop Video Setup itself lost visibility to any HDMI device plugged in. Everything was working fine with the initial installation.

I also had this issue when I originally installed "everything", a newly built DIY computer, Windows 10 20H2 installation with a BM Quad HDMI Recorder.
